Sihe Stainless inventory now includes 310H Plate and Processed Flat Bar (Alloy 310H UNS S31009), ideally suited for high-temperature applications such as heat treatment and chemical processing equipment. Alloy 310H (UNS S31009) has a carbon content restricted to exclude the lower end of the 310 range. This makes 310H the grade of choice for high temperature applications. This steel has good resistance to oxidation at temperatures of up to 1040°C (1904°F) in intermittent service and 1150°C (2102°F) in continuous service; however it is recommended that this steel should not be continuously used at 425-860°C (797-1580°F) range due to carbide precipitation.
